The 240B and M2 cycle of operations includes which sequence of steps?

• A. Feeding, chambering, locking, firing, unlocking, extracting, ejecting, cocking
• B. Feeding, chambering, locking, firing, unlocking, ejecting, cocking
• C. Feeding, chambering, firing, locking, unlocking, extracting, ejecting, cocking
• D. Feeding, chambering, extracting, firing, locking, ejecting, cocking, unlocking

Answer: (A)

One complete firing cycle for the 240B and M2 follows this sequence from a new round being fed to the gun ready for the next shot: a round is fed from the belt and chambered, the bolt then locks to secure the round, the round is fired, the bolt unlocks and begins its rearward travel, the spent cartridge is extracted and ejected, and finally the mechanism cocks so the gun is ready for another cycle. This order ensures the round is securely chambered before firing, and that the spent case is properly removed before the next round can be chambered. Skipping or rearranging steps like locking before firing or extracting before unlocking would prevent proper operation, which is why this sequence is the correct one.
